Abstract

The invention relates to a magnesium / hydroxyapatite composite material and a preparation method thereof. The magnesium / hydroxyapatite composite material is prepared by mixing magnesium and hydroxyapatite serving as raw materials in a mass ratio of 80.5-99.9 percent: 0.1-19.5 percent for molding and sintering the mixture in a vacuum microwave sintering furnace. The composite material provided by the invention has proper mechanical property and can meet the requirements on human body bone tissue materials. A microwave sintering method is adopted, so the method has the advantages of high temperature rise speed, short sintering time, short preparation period, low energy consumption and no pollution.

Description

technical field

[0001] The invention relates to a magnesium / hydroxyapatite composite material and a preparation method thereof, in particular to a preparation method for preparing a magnesium / hydroxyapatite composite material by a microwave sintering method. Background technique

[0002] With the gradual improvement of people's health requirements, biomedical bone tissue substitute materials are playing an increasingly important role in the field of human medicine. However, the currently commonly used bone tissue replacement materials cannot meet the needs of human beings. The elastic modulus of metal biomaterials such as titanium alloy and stainless steel is much higher than that of human bone, which is easy to cause stress shielding effect; the fracture toughness of ceramic biomaterials is extremely low; and The strength of polymer biomaterials is very low. As a new type of biomedical material, magnesium / hydroxyapatite composite material has a much higher fracture strengt...
